# We need to keep the compatibility with older Replicant versions, at least for
# testing purposes: some of the devices we support in libsamsung-ipc are not
# supported (yet) in newer Android versions or recent GNU/Linux distributions,
# and doing tests on older devices might enable us to also understand better
# the modem protocol and/or the EFS.

# To limit the amount of work, we need to avoid modifying older Android versions
# to be able to use recent libsamsung-ril and libsamsung-ipc.

# Here's how different Android distributions behave with
# LOCAL_PROPRIETARY_MODULE := true in libsamsung-ipc's Android.mk:
# Replicant  4.2: It probably breaks the modem support
# Replicant  6.0: It break the modem support
# Replicant  9.0: The modem integration doesn't work because it was not finished
# Replicant 10.0: The modem integration doesn't work because it was not finished
# Replicant 11.0: It is required for the modem to work

# Set a default value for build systems like Guix
